The BSII CheatSheet provides a detailed overview of various functions and parameters related to sound synthesis, covering a range of features from filter tracking to envelope settings and oscillator adjustments.
In the first section, the cheat sheet notes a version 2.5, detailing functions such as Filter Tracking, which utilizes the Mod Wheel to adjust Filter Frequency with values ranging from F0 (ON) to F7 (OFF), corresponding to NRPN 0:108. Another function, Paraphonic, allows for Oscillator Sync adjustments between Osc1 and Osc2, with values from P0 (OFF) to P1 (ON), noted as NRPN 0:107. The Micro Tuning function enables global tuning adjustments with values ranging from t0 (Standard) to t8 (Tune Tables). The Envelope Re-trigger function is available for both AmpEnv and ModEnv, allowing for velocity-based control with values of r0 (Re-trig OFF) to r1 (ON), with NRPN codes 0:109 and 0:110 respectively. Additionally, the Oscillator Error function adjusts Pitch Bend Range from E0 (OFF) to E6 (approximately 1 Semitone), marked as NRPN 0:111.
Transitioning to version 4.14, the cheat sheet introduces several envelope functions, including Fixed Duration for both AmpEnv and ModEnv, which can be set from d0 (Duration OFF) to r1 (ON), with NRPN codes 0:114 and 0:115. The Re-trigger Count for AmpEnv and ModEnv allows for a range from c0 (Indefinite) to c16 (number of loops), documented as NRPN 0:117 and 0:118. Glide Divergence is another global function, controlling Input Gain with values from g0 (Off) to g15 (OSC2 Glide Speed), noted as NRPN 0:113.
The Sub-Oscillator settings include Coarse Detune, adjustable from -12 to +12, with a default of 0 tuned with OSC1, and Fine Detune, which ranges from -100 to +100, also defaulting to 0 when tuned with OSC1, recorded as NRPN 0:84 and NRPN 0:77 respectively. The AFX Mode section includes functions for selecting overlays, modifying hold keys to adjust synth parameters, saving overlays, and clearing overlays. The Copy function allows users to hold a key to be copied and press a key for the destination. The Protect function, associated with Arp, controls Seq-Retrig and can be set to r0 (R/O Disabled) or r1 (R/O Enabled), noted as NRPN 0:116.
Lastly, the cheat sheet provides a reference for Tune Tables, listing values from t0 (Standard) to t4 (Ptolemy), with corresponding names for each tuning table. The values are as follows: t0 is Standard, t1 is Prime, t2 is Harmonic, t3 is Indian, and t4 is Ptolemy.
